Development of a Java-Oriented Software General Component Library

In order to promote the reuse ability of software, the domain engineering-based development method is used. A design architecture and software architecture in domain information system are presented. The paper emphasizes model architecture of domain information system and the design of the general component library. The system implements a general component library to mark, inspect, classify and administrate components. Supported by the JavaBeans, analysis process of component library in UML is described. The general component library is high in class inheritance, low in class coupling, high in class sealing, low in class diversifying, high in efficiency of method reuse and efficiency of class reuse. It provides technical ensure to quickly reconstruct application system.
